Answer:

B. 7/20

Step-by-step explanation:

P(A | B) = P(A∩B) / P(B) is the formula for conditional probability

             = (7/40) / (1/2)

Copy dot flip

              = 7/40 * 2/1

If x/y + y/x = -1 , ( x unequal y, y unequal 0) then the value of x^2 - y^2 is?
Maurinko [17]

Take your original equation \frac{x}{y} +\frac{y}{x} =-1

and multiply both sides by xy to remove the fractions. You are left with

x^2+y^2=-xy

So, x^2+y^2=-xy

Update: There is no numerical answer that can be found without being given a value for either x or y

Solve for X and round to the nearest hundredth
Archy [21]

Answer:

Pretty sure it's 20.24.

Step-by-step explanation:

Since you know the side adjacent to the reference angle and you want to find the side opposite, you're going to need to use tangent, which is opp/adj.

tan(39) = \frac{x}{25}

Find the tangent of 39...

0.8097 is the approximate value. So...

0.8097 = \frac{x}{25}

Now, switch the sides to make it easier.

\frac{x}{25} = 0.8097

Multiply both sides by 25.

x = 20.24
